log4net - 何时调用 FileAppender.Append(LoggingEvent[] loggingEvents)？

Question

我有一个 FileAppender，通常事件是通过 Append(LoggingEvent loggingEvent) 方法登录的，所以每次只有一个事件。我有一个问题，在哪些情况下会调用 Append(LoggingEvent[] loggingEvents) 方法？我知道当有一系列事件要记录时，但我的问题是，我如何模拟一系列事件的情况？为了调用 FileAppender.Append(LoggingEvent[] loggingEvents) 必须发生什么？

Answer 1

You are right: if you use "just" a FileAppender each event is logged via the Append(LoggingEvent) method.

The other method call is fired when you are buffering events via, for example, the BufferingForwardingAppender: it will keep events in memory until some conditions are met, then it will call Append(LoggingEvent[]) on its inner appenders.
